The problem appears to be that auth doesn't have a toJson method on it when it is retrieved from the cache.

This is where calling popup retrieves from the cache:
https://github.com/oauth-io/oauth-js/blob/master/coffee/lib/oauth.coffee#L89

This is where toJson is called if it exists:
https://github.com/oauth-io/oauth-js/blob/master/coffee/lib/user.coffee#L139

This is where toJson is defined:
